SKI LOCK BACKGROUND l. Field of the Invention This invention relates to a locking device for securely engaging a pair of skis together and may include a device for securing the lock to a third object.

2. The Prior Art With the increased emphasis upon skiing as a recreation, there has been a corresponding increase in theft of skis. Generally, skis are removed from where the owner or user has temporarily deposited them, usually at rest or refreshment areas adjacent ski slopes or from automobile racks with removal being accomplished, for example, by a person exchanging a less valuable pair of skis for the more valuable pair of skis and then skiing or walking away with the newly acquired skis. To thwart this practice, it has become customary for skiers to use various ski restraing devices; for example, see US. Pat. Nos. 3,636,739; 3,742,740; 3,461,696; and 3,727,934.

The first reference above discloses a device having at least two separate parts which combine to securely engage the skis. Bulk is thereby increased and the chances of the parts becoming separated are greater. The latter three references disclose ski locking devices which require the physical alteration of the skis before the devices can be used to lock the skis.

It would therefore be desirable to provide a ski locking device which is compact and thus easily portable, unitary to preclude loss of one part, and adaptable for noninjuriously securing a pair of skis to a third object.

BRIEF SUMMARY AND OBJECTS OF THE INVENTION The present invention is a ski locking device for rigidly clamping a pair of skis with their sliding surfaces juxtaposed. A pair of skis, unidirectionally oriented and with their respective sliding surfaces juxtaposed, present a profile wherein a segment of the skis immediately to the rear of the upturn exhibits, in cross section, the smallest combined cross-sectional area for the pair of skis so placed. This segment extends for a relatively short distance rearwardly. Beyond this segment, the combined cross-sectional area of the skis increases from the greater thickness of each ski and also from the reverse curvature of each ski wherein the skis are away from each other. Accordingly, a portable lock which rigidly clamps and closely encircles the skis at the foregoing segment of smallest combined cross-sectional area will securely engage one ski to the other. Any attempt to slide one ski relative to the other and through the lock will be firmly resisted since each ski either increases in cross-sectional area or has a relatively short radius curvature which prevents movement of the ski through the lock.

It is, therefore, an object of this invention to provide improvements in the art of securing a pair of skis.

It is another object of this invention to provide a unitary ski locking device that is compact and relatively lightweight for ease of carrying.

It is another valuable object of this invention to provide a ski lock which snugly engages a pair of skis at their point of smallest combined cross-sectional area.

It is an even further object of this invention to provide a ski locking device having an integral securement device for permitting securement of the ski lock to another object.

It is an even still further object of this invention to provide a ski locking device which securely engages a pair of skis to each other in the absence of alteration of the skis.

It is an even still further object of this invention to provide a method for securing together a pair of skis.

It is an even further object of this invention to provide a ski locking device having an integral combination lock.

These and other objects and features of the present invention will become more fully apparent from the following description and appended claims taken in conjunction with the accompanying drawing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In General The invention is best understood by reference to the Figures wherein like parts are designated with like numerals throughout.

Skis have a uniform width but a variable crosssectional area and curvature along their length to give the skis the desired flexibility. A close-fitting lock 20 placed on a pair of skis 23 and 25 immediately behind the upturn of the skis engages skis 23 and 25 at their point of smallest combined cross-sectional area. With lock 20 being snug-fitting and rigid, the skis are firmly held and it is impossible to move the lock 20 from its locked position without damaging the skis. Movement of either ski in a forward or a reverse direction relative to the lock is prevented since each ski increases in cross-sectional area in either direction from where the lock is placed.

The Embodiment of FIGS. l5

Ski lock 20 comprises two rigid jaws 22 and 24 hinged at one end about hinge pin 28 and dimensionally adapted to snugly encircle a pair of skis at a point of least combined cross-sectional area. A bracket receiving slot 44 in either jaw 22 or 24, shown here in jaw 24, adapts the ski lock 20 to receive a fixed bracket 21 (FIG. 5), in addition to the skis, to thereby secure the skis to the bracket 21.

In the locked position, as shown in FIG. I, lock engaging prongs 30 (shown in broken lines) engage matching locking members (not shown) of a combination lock 32. A plurality of numbered combination actuating wheels 34 are rotatable to present a plurality of possible lock combinations (see also FIG. 4). Conventionally, the lock combination is selectively preset to release lock engaging prongs 30 when the wheels 34 are rotated to the preset combination position.

Felt pads 36 desirably line a portion of all ski contacting interior faces of jaws 22 and 24 to preclude injury to the skis 23 and 25. A spline 38 (shown in broken lines) on an interior face of jaw 22 serves to engage a keyway 40 (FIG. 2) of a spacer block 42. The spacer block normally is interposed in a receiving area adjacent spline 38 as shown in broken lines in FIG. 6. Jaw 22 is adapted to receive spacer blocks of varying thicknesses to enable lock 20 to accommodate skis of varying widths.

Jaws 22 and 24 engage skis 23 and 25 and through slot 44 a bracket 21 (FIG. to simultaneously securely affix the skis to a stationary wall 70 provided with bracket 21. Even if the notch 44 is not used to engage bracket 21, the lock is still usable as a device for securing a pair of skis together because the slot 44 may be smaller than the width of jaw 24.

Referring now to FIG. 2, spacer block 42 is more clearly shown to reveal keyway 40 which engages spline 38 (FIGS. 1 and 6). Felt pad 36 on a face of spacer block 42 also serves to protect the skis from damage.

Reference is now made to FIG. 3 showing the hinge arrangement of hinge 26, to be configured as a pianotype hinge. Additional hinge strength in hinge 26 is obtained by providing a plurality of intermeshing fingers 46 and 48 which rotate about the transversely penetrating hinge pin 28. Hinge pin 28 may have a conventional rounded head 50 or, preferably, a countersunk head 52.

Referring to FIG. 6, hinge 26 and lock 32 engaging portions 30 of ski lock are more clearly shown. In particular, the lock engaging members 30 (shown here as a plurality) are received into recesses 31 of lock 32 when the ski lock 20 is closed.

Conventionally, a reset lever 54 enables the owner of the lock to readily alter the lock combination to any preselected combination setting of his choosing. Lever 54 is operable in a recess 55 in an internal face of bracket 22 to preclude tampering with the lock mechanism. Internal mechanism of lock 32 prevents alteration of the combination unless the lock is opened. The feature of lever 54 is presently commercially available.

The Embodiment of FIG. 7

Referring now to FIG. 7, one desirable modification of the ski lock is shown whereby the lock is adapted to receive both ends of a discrete length of a tether which may be any suitable device such as a chain, cable, or the like. For sake of simplicity, a chain is shown in the illustrated embodiments. In this preferred embodiment, a chain 66 (shown as broken, for sake of simplicity) has one end affixed to jaw 22 of ski lock 20 with the other end attached to a lock engaging collar 58. Collar 58 comprises a rectangular metal annulus having beveled internal faces 60 which match the beveled faces 63 of a recess 65. Recess 65 girdles ski lock 20 at its locking interface. Functionally, collar 58 closely engages lock 20 as shown by broken lines 58a to present a smooth external surface to hinder tampering with the lock. Even with ski lock 20 closed and without collar 58 being in place, beveled edges 63 greatly hinder tamper ing with lock 20 by inclining the surface against which leverage could be applied.

A further modification (not shown) of the foregoing is to split collar 58 into two matching bands which mate to fit in recess similar to collar 58 and with each end of chain 66 attached to one of the bands. In this manner, the chain could easily be dispensed with entirely at the discretion of the user. However, it is preferable to have each part of the ski lock securely attached together to preclude loss of a part. Obviously, other ar rangements for shackling the ski lock to a third object are possible. However, for ease of presentation, the number has been reduced to that of the disclosed em bodiments.

The Embodiment of FIGS. 8 and 9 Referring to FIG. 8 and 9, a further hinge embodiment is shown whereby jaws 22 and 24 cooperate in hinged relation through a discrete arcuate distance from the closed position and are thereafter separable. Interlocking extensions 62 and 64 of jaws 22 and 24, respectively, are adapted to receive each other in interlocking relationship when lock 20 is closed. Movement of shackles 22 and 24 beyond the discrete are, upon opening of ski lock 20, permits separation of extensions 62 and 64 and, consequently, jaws 22 and 24.

Being thus separable, and with an end of a chain 67 attached to each ofjaws 22 and 24, lock 20 permits facile securement of the skis together and, if desired, securement to a stationary object with either chain 67 or notch 44 about bracket 21 (FIG. 5). Complete separation of jaw 22 from jaw 24 is prevented by chain 67.

Lateral movement of extensions 62 and 64 parallel to the axis of rotation is prevented by side members 68, one being broken away and shown in broken outline to more clearly reveal extension 62 and the cooperation between extensions 62 and 64.

The bracket receiving slot 44 permits the lock to engage a bracket along with the skis to thereby secure the skis to the bracket. In addition, the integral chain 66 or 67 permits facile securement of the lock to a post, rack, or other such fixed object. Resistance to unauthorized removal and/or separation of skis 23 and 25 is therefore governed by the strength of ski lock 20 and/or chain 66 or 67.

The ski lock disclosed herein has the additional advantage in that it secures the pair of skis in their conventional carrying position, that is, with both skis unidirectionally oriented and placed with their sliding surfaces in contact. With both skis securely bound to each other bythe lock, the skis are easily carried as a single unit.

Advantageously, the ski lock of the present invention is compact and is thus easily portable yet strong enough to resist the unauthorized separation of the skis. Attempts at separation will, in all probability, result in damage to the skis.

Use of the ski lock, even in the absence of the restraining chain or its non-use, will serve as a deterrent to unauthorized removal of the skis. Removal of the ski lock, without unlocking the same, will require extensive effort in secrecy and the use of tools. Even under these conditions damage to the skis will, in all probabilcharacteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive and the scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
